Abstract

Recently, Duda et al. [J. C. Duda, P. E. Hopkins, Y. Shen, and M. C. Gupta, Phys. Rev. Lett. 110, 015902 (2013)] reported that the fullerene derivative [6,6]-phenyl-C${}_{61}$-butyric acid methyl ester (PCBM) has the lowest thermal conductivity \ensuremath{\Lambda} ever observed in a fully dense solid, \ensuremath{\Lambda} \ensuremath{\approx} 0.03 W m${}^{\ensuremath{-}1}$ K${}^{\ensuremath{-}1}$. We have investigated a variety of phases and microstructures of PCBM and the closely related compound [6,6]-phenyl-C${}_{61}$-butyric acid n-butyl ester (PCBNB) and find that the thermal conductivities of PCBM and PCBNB films are mostly limited to the range 0.05 \ensuremath{\Lambda} 0.06 W m${}^{\ensuremath{-}1}$ K${}^{\ensuremath{-}1}$ with a few samples having slightly higher \ensuremath{\Lambda}. The conductivities we observe are \ensuremath{\approx}70$%$ larger than reported by Duda et al. but are still ``ultralow'' in the sense that the thermal conductivity is a factor of \ensuremath{\approx}3 below the conductivity predicted by the minimum thermal conductivity model using an estimate of the thermally excited modes per molecule.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • TDTR is often used to measure the through-plane thermal conductivity Kz of the sample and the transducer/sample interface conductance G without much elaboration.

  • Ultra-low thermal conductivities of full-dense solid materials were reported for fullerene derivatives at room temperature (~0.05 W m-1 K-1) and disordered layered WSe2 thin films at cryogenic temperatures (~0.03 W m-1 K-1), both measured using TDTR.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
